Just a few days ago, some Magic Kingdom Park Guests were able to spot a familiar face around Adventureland. Indeed, Rafiki (the wise mandrill seen in Disney's animated movie The Lion King) began greeting Guests near the Swiss Family Treehouse (his rain location will be near the Sunshine Tree Terrace).
Additionally, Stitch is no longer greeting Guests in Tomorrowland. He can still be seen daily as part of the Move It! Shake It! Dance & Play It! Street Party.
